Letters Patent No. 84,262, dated November 24, 1868'.

IMPROVEMENT IN WATER-CLOSETS.

arr- The Schedule referred to in these Letters Patent and making part of the same.

To all whom it ma/y concern.'

Be it known that I, HUGH HQORAIGIE, of the cit and State of New York, have invented, made, and ap,- plied to use, a certain new and useful Improvement in Cocks for Water-Closets; and I do hereby declare the following to bea full, clear, and exact description of the `said invention, reference being had to the annexed drawing, making part of this specication, wherein- Figure 1 is a vertical section of the said cock as closed;

o Figure 2 is a similar view of the said cock in the position the parts assume while'the piston is being pressed down and Figure 3 is a section of the cocks1 with the parts in the position they assume as the water commences to run.

Similar marks of reierence denote the same parts.

Theiobject of this invention is to provide a valve or cock for water-closets that is acted upon by a connection to the seat, and moved when the person sits down, but the' water does not commence to How until the weight is taken oii the seat, and the valve closes gradually, allowing the water to run thedesired length of time. This cock, however, may be moved by a connection to the pull or lever of the closet.

In Letters Patent granted to me December 31, 1867, a cock is shown, in which the chamber that contains water, to regulate the gradual closing of the valve, is on the same side of the valve as the inlet of the water, and hence is always iilled. The same character of chamber is employed lin the present'valve, but the arrangement and construction of the' parts are di'erent.

My present invention relates to a valve, applied to a piston, and rod to admit the water into the chamber that controls the valve, and said valve closes as the chamber comes into operation. f Also, to a sliding piston and valve, combined with a stationary seat,

and arranged in such a manner that said valve has a seat on both sides of it, and when closed upon the seat of the piston, keeps that tight, and when closing upon the stationary seat, prevents the water passing to the closet, but while in an intermediate position, the water runs through the piston and stationary seat to the water-closet.

In the drawingais the cylinder, forming the valve-controllin g chamber. This is supported by a flange or other convenient means of attachment to the platform or closet.

b is the cylinder, forming the passage-way between v the inletpipe c and outlet-pipe d, and in which is the stationary valve-seat f.

g is a screw-cap, with the valve-opener c, actuated from the water-closet seat, or from the pull or lever, in any convenient manner. This is shown as formed with a diaphragm, c', and lifting-spring k, but the valve-opener may pass through a stuffing-box or other packing.

The piston l is on a rod, m, and said piston is formed as a ring, receiving the valve u, the body of which valve sets within said ring, and has lips 1 l to limit the motion and prevent the valve getting out of place, but grooves or channels in said body allow the-.water to pass freely through the ring-piston.

The leather or elastic face, 2, of the valve n, makes said valve tight, whenlinv contact with the seat 3, of the piston n, or when in contact with the seat j, and

when both are in contact with said leather 2, Aas in iig. v

l, leakage through the cock becomes impossible. v F The spring p acts to lift the piston l. The :flow of water also acts inthev same direction.

It will now be understood-that the closing-movement of the valve'and piston being rendered gradual by a controlling water-chamber or other device, (such devices are known; one special construction is hereafter described,) the operation will be as follows:

The valve-opener h being moved, acts against the valve n, moving that away from' the seat f, and also moving the piston Z, (see iig. 2,) but water cannot pass said piston, because the valve n keeps its opening closed, but the moment Ithe opener h is relieved, the pressure of Water lifts the valve n, allowing the water to run through the piston l, as indicated in iig. 3, until, by the gradual movement of the piston Z, the valve n reaches the seat f, shutting oli" thefurther iiow of water to the closet.

The piston lis packed with leather washers, or other suitable material.

The piston-rod m is made hollow, with an opening at 6, so -that water can eely pass into the chamber A slight play is allowed of the rod, endwise, through the piston s, and grooves are formed at this point, as at 8.

It will now be understood that the piston-rod m,

when depressed, moves the nut fr and washer 7 from contact with the piston s, allowing the water to pass from one side of the piston sto the other, through the slots 8, as the piston is moved along with the rod m, as indicated in iig. 2, but as soon as the pressure of h is removed, the piston-rod moving endwise, closes i the openings 8, by the washer 7, (see iig. 3,) and the water confined in the chamber, between the piston s' and diaphragm q, controls the movement of the watercloset valve in closing, as the water is forced out of the chamber. Y f

The leakage upward, around the piston-rod m, al

lowsthe valve to close gradually in the desired length of time, and the proper amount of water to run into the closet.

The extent of motiongiven to the valve will determine the length of time that the water is allowed to run to the closet.

It will be evident that instead of the Water passing through the hollow piston-rod m, a connection might be made from the pipe c to the lower end of the cylinder a, or a separate cylinder, with a head taking the place of the diaphragm q, might beintroduoed within' the cylindrical part of the cook.

If the piston s were attached firmly to the end of the rod lm, the nut fr and leather 7 might be applied around the piston-rod m, at the diaphragm q,lin the form of a ring-valve, that would slide, to allow the inletof Water to the chamber, or olose vto oonne said Water, and control the closing of the closet by the gradual leakage.

What I claim, and desire to secure by Letters Patent, is

1. The piston l, moving in the cylinder b, betweeh the inlet and outlet-pipes, in combination 'with the valve n and seat f, the parts being arranged and-oper` ating substantially as and for the purposes set forth.

2. The rod m, piston s, and valve'controll'mg chamber a, in combination, with the water-Way 8, and valve n, to the Water-closet, substantially as speoiiied, so that the end-movement givento the piston-rod shall open or close the water-Way 8, for the purposes specified.

3. The' valve l", applied at the piston-rod m, in oombination, with the valve-controlling chamber a, and`a piston, moving in said chamber, to regulate the clos ing of a water-closet valve, substantially as set forth.

In witness whereof, I have hereunto set my signature, this 30th dayiof January, A. D. 1868.
